[0030] See also Figure 1 to Figure 2 As shown, a laser marking guide device includes a horizontally arranged base 1, which can be placed directly on the ground. A laser marking machine 2 is fixed on the base 1, and a movable focusing component 3 that can move vertically is provided below the laser marking machine 2. The distance between the movable focusing component 3 and the laser marking machine 2 is adjusted by controlling the vertical movement of the movable focusing component 3, so as to ensure that the laser marking machine 2 achieves focusing. A feeding mechanism 4 is also provided on the base 1, and the workpiece can be moved from the feeding mechanism 4 to the movable focusing component 3, and then the height of the workpiece is adjusted by the movable focusing component 3, and the exposed part of the workpiece is adjusted at the same time, so that the marking part of the workpiece is aligned with the laser marking machine 2 and the focus of the workpiece is achieved, thereby completing the marking. This solution is mainly aimed at the precise marking of ball valves and other spherical workpieces.

[0031] The above-mentioned movable focusing component 3 includes a base plate 5 and a vertical lifting mechanism 6. The vertical lifting mechanism 6 is located below the base plate 5 and is fixed to the lower surface of the base plate 5. At the same time, the lower end of the vertical lifting mechanism 6 is fixed to the base 1. The vertical lifting mechanism 6 can control the vertical movement of the base plate 5, thereby adjusting the distance between the base plate 5 and the laser marking machine 2. Here, the vertical lifting mechanism 6 can be set to an electric telescopic rod or a hydraulic cylinder, as long as it can drive the base plate 5 to move vertically.

[0032] See also Figures 3 to 5 As shown, the feeding mechanism 4 includes a storage box and a feeding channel 7. The workpiece is placed in the storage box and can enter the feeding channel 7 from the storage box. Specifically, the storage box includes an outer barrel 8 and an inner rotating barrel 9. A bracket 10 is fixed on the base 1. The outer barrel 8 is fixedly placed above the bracket 10. The inner rotating barrel 9 is movably connected to the inner part of the outer barrel 8. The outer barrel 8 is a cylindrical structure with an open upper end. An annular baffle 11 is installed between the outer barrel 8 and the inner rotating barrel 9. The lower end of the annular baffle 11 is fixed to the bottom surface of the outer barrel 8, and the bottom surface between the outer barrel 8 and the annular baffle 11 is set as an inclined guide The annular baffle 11 is provided with a partition plate 13 in an array, one end of the partition plate 13 is fixed to the annular baffle 11, and the other end is fixed to the inner wall of the outer barrel 8, the bottom surface of the partition plate 13 is in contact with the inclined guide surface, and the area between every two partition plates 13 is set as a storage area 14, and the workpiece is placed in the storage area 14. At this time, a discharge port 15 is opened on the annular baffle 11, and each storage area 14 is correspondingly provided with a discharge port 15, so that the workpiece in the storage area 14 can be guided by the inclined guide surface to move to the discharge port 15 and be removed from the discharge port 15;

[0033] The inner drum 9 is a cylindrical structure with two ends open. A rotary dial coupling frame 16 is fixedly connected to the inner wall of the inner drum 9. The lower surface of the rotary dial coupling frame 16 contacts the bottom surface of the outer drum 8. At the same time, a rotating shaft 17 passes through the bottom surface of the outer drum 8. The upper end of the rotating shaft 17 is located in the inner drum 9 and is fixedly connected to the rotary dial coupling frame 16. The lower end of the rotating shaft 17 extends downward to penetrate the bottom surface of the outer drum 8 and is connected to a power source 18. The power source 18 is fixed to the bracket 10. The power source 18 can drive the rotary dial coupling 16 to rotate through the rotating shaft 17, thereby driving the inner drum 9 to rotate, and the centers of the rotating shaft 17, the inner drum 9 and the outer drum 8 are all coincident; the rotary dial coupling 16 includes two toggle plates 19, one end of each of the two toggle plates 19 is fixed to the rotating shaft 17, and the other end is fixed to the inner wall of the inner drum 9, and a fan-shaped material storage space 20 is provided between the two toggle plates 19, so that the inner drum 9 and the rotary dial coupling 16 can be rotated synchronously;

[0034] At this time, a docking port 21 of the same size as the discharge port 15 and in the same horizontal plane is opened on the inner drum 9. The docking port 21 is located between the two toggle plates 19 and is connected to the storage space 20. During the rotation of the inner drum 9, the docking port 21 will rotate until it is aligned with the discharge port 15, so that the workpieces in the storage area 14 can fall from the discharge port 15 and the docking port 21 into the storage space 20 between the two toggle plates 19. The size of the storage space 20 can only store one workpiece. When there is a workpiece in the storage space 20, even if the docking port 21 is aligned with the discharge port 15 again, the workpieces in the storage area 14 cannot continue to enter the storage space. Space 20; as the inner drum 9 continues to rotate, the toggle plate 19 continues to rotate and toggle the workpieces in the storage space 20 to move. At this time, a drop port 22 is opened on the bottom surface of the outer drum 8, and the drop port 22 is located below the inner drum 9. The diameter of the drop port 22 must be larger than the diameter of the discharge port 15 and the docking port 21 to ensure that the workpiece can smoothly fall from the drop port 22. When the docking port 21 is aligned with the discharge port 15, the workpiece in the storage area 14 falls into the storage space 20, and then the two toggle plates 19 rotate until the drop port 22 is located between the two toggle plates 19, and the workpiece in the storage space 20 will fall from the drop port 22, so that the workpiece is separated from the storage box.

[0035] The feeding channel 7 is located below the drop port 22, and a notch 23 is provided at one end of the bracket 10 close to the base plate 5. The feeding channel 7 is fixedly clamped in the notch 23. The feeding channel 7 is tilted from high to low. The high end of the feeding channel 7 is located between the bottom surface of the outer barrel 8 and the bracket 10, and the low end is tilted downward and extends to the top of the base plate 5. The feeding channel 7 is a strip groove with a "concave"-shaped cross-section. A movable sliding sleeve 24 is slidably connected to the outer surface of the feeding channel 7. The movable sliding sleeve 24 can slide along the length direction of the feeding channel 7, and the lower end of the movable sliding sleeve 24 is always in contact with the upper surface of the base plate 5. When When the base plate 5 moves vertically upward or downward, the movable sleeve 24 will receive an upward thrust or its own gravity and move upward or downward with the base plate 5. This arrangement avoids the situation where a gap is created between the feeding channel 7 and the base plate 5 when the base plate 5 moves vertically, causing the workpiece to fall from the base plate 5. The movable sleeve 24 provides a guiding function between the feeding channel 7 and the base plate 5, ensuring that the workpiece in the feeding channel 7 can smoothly reach the base plate 5. At this time, a guiding member 25 is set in the base plate 5, and the workpiece will contact the guiding member 25 and be adjusted in position by the guiding member 25, and then the laser marking machine 2 completes the marking.

[0036] See also Figures 6 to 8 As shown, a guide strip opening 26 is provided on the base plate 5, the guide strip opening 26 extends along the length direction of the base plate 5 and is closed at both ends, a shaft rod 27 is fixed in the guide strip opening 26, and the shaft rod 27 is arranged along the length direction of the guide strip opening 26, and a guide member 25 is movably connected in the guide strip opening 26 and can slide in the guide strip opening 26 along the length direction of the shaft rod 27, and the guide member 25 can be horizontally moved to the bottom of the feeding channel 7, so that the workpiece is moved from the feeding channel 7 to the guide member 25, and then the guide member 25 moves in the opposite direction to drive the workpiece to move to the bottom of the laser marking machine 2, so as to realize marking, specifically:

[0037] The guide member 25 includes a guide block 28 and a gear plate 29. The shaft 27 passes horizontally through the middle of the guide block 28. The guide block 28 can slide in the guide strip opening 26 along the length direction of the shaft 27. The gear plate 29 is arranged below the guide block 28. The gear plate 29 can drive the guide block 28 to move horizontally along the shaft 27 in the guide strip opening 26. A flat rack 30 is installed on the lower surface of the guide block 28, and the flat rack 30 is meshed with the gear plate 29. When the gear plate 29 rotates, the flat rack 30 will move horizontally accordingly. At this time, a vertical plate 31 is fixedly connected to the lower surface of the base plate 5, and a driving motor 32 is fixed on the vertical plate 31. The output end of the driving motor 32 is fixedly connected to the center of the gear plate 29. When the driving motor 32 is working, it can drive the gear plate 29 to rotate synchronously, so that the flat rack 30 meshing with the gear plate 29 moves horizontally, thereby driving the guide block 28 to move horizontally in the guide strip opening 26.

[0038] A semicircular groove 33 is also provided on the upper surface of the guide block 28, and a positioning member is movably connected in the semicircular groove 33. When the guide block 28 moves along the guide strip opening 26 to below the feeding channel 7, the feeding channel 7 corresponds to the guide strip opening 26, and the workpiece falls from the feeding channel 7 into the semicircular groove 33 on the guide block 28 and contacts the positioning member. The positioning member adjusts the position of the workpiece to expose the marking part of the workpiece, so as to facilitate the laser marking machine 2 to perform accurate marking. Specifically:

[0039] Two horizontally arranged adjustment grooves are arranged in the guide moment block 28, and both adjustment grooves are connected to the semicircular groove 33, one of which is an active adjustment groove 34, and the other is a passive adjustment groove 35. The adjustment member includes a rotating rod 36 and a sliding rod 37, and the rotating rod 36 and the sliding rod 37 are both arranged vertically with the guide strip opening 26. One end of the rotating rod 36 is located in the active adjustment groove 34 and is movably connected to the inner wall of the active adjustment groove 34, and the other end penetrates the guide moment block 28 and the base plate 5 and extends to the outside of the base plate 5. A There is an adjustment notch 54, which is connected to the guide strip opening 26. When the guide moment block 28 moves horizontally, the adjustment rod 36 slides horizontally in the adjustment notch 54, and the rotating handle 38 is connected to the end of the rotating rod 36 located outside the base plate 5. The rotating handle 38 can drive the rotating rod 36 to rotate. At this time, two active wheels 39 are fixedly sleeved on the rotating rod 36. The two active wheels 39 are both located in the active adjustment groove 34. The circumferential surface of the active wheel 39 is distributed with convex teeth, and the sliding rod 37 is located in the passive adjustment groove 34. In the adjustment slot 35, spring channels 40 are symmetrically opened on the two side walls of the passive adjustment slot 35, and the two ends of the slide rod 37 are fixedly connected with square pads 42, which are slidably connected in the spring channel 40, and a return spring 41 is arranged in the spring channel 40, and the two ends of the return spring 41 are respectively fixed to the spring channel 40 and the square pad 42. When the square pad 42 drives the slide rod 37 to slide in the spring channel 40 in the direction close to the guide moment block 28, the return spring 41 will be stretched and generate a restoring force. Two driven wheels 43 are movably mounted on the slide bar 37. The two driven wheels 43 correspond to the driving wheels 39 on the rotating rod 36 respectively. The driven wheels 43 can rotate around the slide bar 37 and have a smooth surface. A conveyor belt 44 is arranged between the corresponding driving wheels 39 and the driven wheels 43, that is, two groups of conveyor belts 44 pass through the semicircular groove 33. There are evenly distributed pits on the conveyor belt 44. The convex teeth on the driving wheel 39 will fit in the pits. Then, when the handle 38 is rotated, the conveyor belt 44 can achieve horizontal movement.

[0040] See Figure 9 to Fig.10As shown, the above-mentioned laser marking machine 2 is fixed to the base 1 through a positioning frame 45, and a translation auxiliary component 46 is sleeved on the positioning frame 45. The translation auxiliary component 46 is located between the laser marking machine 2 and the base plate 5. An annular groove 47 and a locking groove 48 are provided on the outer surface of the positioning frame 45. The locking groove 48 is vertically arranged and the upper end is connected with the annular groove 47. The translation auxiliary component 46 includes an outer sleeve 49 and an adsorption combination plate. A protrusion 50 is provided on the inner wall of the outer sleeve 49. The protrusion 50 can be matched in the annular groove 47 and rotate in the annular groove 47. When the protrusion 50 rotates to the position where the annular groove 47 is connected with the locking groove 48, the protrusion 50 will enter the locking groove 48 under the action of gravity, and the locking groove 48 will prevent the protrusion 50 from continuing to rotate, thereby achieving the outer sleeve 49. The position of the cylinder 49 is locked, an extension arm 51 is fixedly connected to the outer sleeve 49, and the adsorption combination disk is connected to the free end of the extension arm 51. The adsorption combination disk includes a positioning ring 52 and an adsorption ring 53. The positioning ring 52 is fixed to the extension arm 51, and the adsorption ring 53 is slidably connected to the inner surface of the positioning ring 52. The adsorption ring 53 coincides with the center of the positioning ring 52, and a suction cup 55 is distributed in a circular array on the inner surface of the adsorption ring 53. When the protrusion 50 in the outer sleeve 49 is engaged in the locking groove 48, the laser beam emitted by the laser marking machine 2 passes through the center of the adsorption ring 53. At this time, a plurality of ball bearings are arranged on the inner wall of the semicircular groove 33. When the workpiece falls into the semicircular groove 33, the ball bearings can reduce the friction between the workpiece and the semicircular groove 33, so as to help the workpiece to adjust its position.

[0041] When the workpiece falls into the semicircular groove 33 from the feeding channel 7, the workpiece will contact the ball and the conveyor belt 44 in the semicircular groove 33 at the same time, and the driving motor 32 controls the guide moment block 28 to move below the laser marking machine 2 until the laser beam emitted by the laser marking machine 2 falls on the center of the semicircular groove 33. At this time, the protrusion 50 on the outer sleeve 49 is located in the locking groove 48, so the center of the semicircular groove 33 and the adsorption ring 53 are on the same vertical line. Then, the vertical lifting mechanism 6 controls the base plate 5 to move upward until the workpiece in the semicircular groove 33 contacts the suction cup 55 on the adsorption ring 53 and is stably adsorbed by the suction cup 55. , then control the adsorption ring 53 to rotate in the positioning ring 52, so as to rotate the workpiece horizontally, and then by rotating the handle 38, the conveyor belt 44 will move horizontally and drive the workpiece to rotate vertically, until the laser beam emitted by the laser marking machine 2 falls on the marking part of the workpiece, at this time, the outer sleeve 49 is moved upward until the protrusion 50 is separated from the locking groove 48, and then the outer sleeve 49 is rotated 180° so that the adsorption combination disk is located on the back of the laser marking machine 2, and then the vertical lifting mechanism 6 is controlled to drive the base plate 5 to move vertically to the laser marking machine 2 to achieve focusing, and the laser marking machine 2 completes the precise marking.

[0042] In the initial state, the discharge port 15 and the docking port 21 are in a staggered state. First, the feeding mechanism 4 is controlled to work, that is, the rotating shaft 17 is controlled to rotate at a constant speed until the discharge port 15 is aligned with the docking port 21, and the workpiece is separated from the storage area 14 and falls into the storage space 20. As the rotating shaft 17 continues to rotate, the workpiece in the storage space 20 falls from the drop port 22 into the feeding channel 7. At the same time, the guide block 28 is controlled to move toward the feeding channel 7, and the guide block 28 is moved to the bottom of the movable sleeve 24 before the workpiece is separated from the movable sleeve 24, so that the workpiece falls into the semicircular groove 33 on the guide block 28, and then The guide matrix 28 is controlled to move toward the laser marking machine 2. When the guide matrix 28 moves to the bottom of the laser marking machine 2, the base plate 5 is moved up until the adsorption ring 53 contacts the workpiece in the semicircular groove 33 and is adsorbed by the suction cup 55. The adsorption ring 53 is rotated to adjust the horizontal position of the workpiece. Then, by rotating the handle 38, the conveyor belt 44 is moved horizontally and the workpiece is driven to rotate vertically to adjust the vertical position of the workpiece until the marking part of the workpiece is accurately aligned with the laser marking machine 2. Then, the vertical lifting mechanism 6 is continued to be controlled to drive the base plate 5 to move vertically, so that the laser marking machine 2 focuses on the marking part to complete the marking.

[0043] See also Fig.11 As shown, in the present invention, two guide members 25 can be provided, and feeding mechanisms 4 are provided at both ends of the base plate 5, so that the two guide members 25 work alternately, thereby improving the marking efficiency.
